Rachel McAdams is one of the most in-demand Canadian actresses, especially in films. Her most notable works include The Hot Chick, Mean Girls, Sherlock Holmes, and The Notebook.

People continue to be curious about her bra size because there are conflicting records about it. I’m setting the record straight about the bra size of Rachel McAdams and how to best style it.

What Bra Size Is Rachel McAdams?

The bra size of Rachel McAdams is 32B. Her small bust measures around 33 to 34 inches. She needs to wear a bra with B cups and a band ranging from 28 to 30 inches.

While they both have a 32-inch bra band, McAdams is still two cups smaller than her Mean Girls co-star Amanda Seyfried, who wears a 32D bra. Similar to Alexis Bledel’s cup size, McAdams’ bust appears almost flat because of her banana-shaped body.

McAdams can size up to 34A or go down to 30C. This suggests she can share similar bra styles with fellow actress Michaela McManus, who has a 34A bra size. It’s best to wear padded t-shirt bras or balconette bras to make their small breasts look bigger.

Rachel McAdams Measurements

Rachel McAdams is average in height, measuring in at 5 feet 4 inches (5′ 4”). I estimate that her body measurements are 34-24-35 inches, which translates to a bust size of 34″, a waist size of 24″, and a hip size of 35”. She weighs roughly 119 pounds.

Benefits of a Small Cup Size

Can Go Braless

One of the best things about being small-chested is that if you don’t want to wear a bra, you don’t have to! At their core, bras are meant to support your boobs, and when you are an A or B cup, you don’t need a bra for this purpose.

Easier to Buy Clothing

Whether you’re shopping online or in stores for clothing, tops and dresses are often initially designed for women with smaller boobs. This gives you more options, and it also means that you won’t need to worry about getting custom-tailored clothing most of the time.

Minimal Bounce During Workouts

One huge benefit of having small breasts is that they hardly affect athletic performance because of their lack of bounce. It can be painful to have your boobs bouncing around as you work out, and women with small chests don’t have to experience this pain. Plus, small boobs mean you can wear pretty much any sports bra style, even if it has minimal padding.

Drawbacks of a Small Cup Size

Sports Bras Can Flatten Breasts Too Much

Sports bras are a must-have in every woman’s wardrobe, even if you have small breasts. However, some sports bras have the potential to flatten your chest by compressing more breast tissue. It’s like watching your small breasts disappear once you wear a sports bra.

Breasts Stay Small as You Gain Weight

If your breasts are dense with tissue, they won’t grow in size even as you gain weight. In turn, they may look significantly smaller as you gain more fat in other parts of your body. However, if you lose weight, the fat in your breasts may also reduce, causing your boobs to become even smaller.

Don’t Always Fill Out Clothing

Despite its several benefits, among the most notable disadvantages of having small breasts is the chance that you won’t fill out bra cups or clothing. Particularly when the breast tissue is leaning toward the bottom, the shallow bustline can cause gaping cups.

Conclusion

Rachel McAdams has a 32B bra size. A small bust makes it easier to wear slip dresses and off-shoulder tops. She can still add volume to her breasts by wearing bras with padded or molded cups.
